According to TMZ, the superstar country couple have filed a legal response to a lawsuit that claims they stole the song, which is the title song and second single from the couple's first-ever duets album. The celebrity gossip site reports that McGraw and Hill claim they lawfully licensed the song, meaning there would be no conflict with them performing it.

TMZ reports they back Sheeran's claim that he did not create a "note for note" copy of a song titled "When I Found You,' which was previously a hit for Jasmine Rae in Australia. The couple also claim that even if Sheeran and his co-writers had lifted the song, that would have nothing to do with them, since they merely recorded a song that was pitched to them and were not involved in its creation.

The Nastiest Lawsuits in Country Music

Songwriters Sean Carey and Beau Golden filed a lawsuit in New York federal court on Jan. 10, claiming "The Rest of Our Life" was obviously stolen from their prior work.

"The copying is, in many instances, verbatim, note-for-note copying of original elements of the Song, and is obvious to the ordinary observer," their filing states. Songwriters Amy Wadge, Johnny McDaid and Steve Mac were also named as defendants in the lawsuit, along with several music companies and publishers.

Sheeran fired back in court on April 2, claiming "The Rest of Our Life" is an "originally and independently created musical composition" that has no relationship to their song.
